Phonegap 3.0 自定义插件

Question

几个月前，我用 phonegap 2.7 为一个应用程序编写了一个插件，它运行良好。该插件基本上会打开用户电话簿并将用户选择的联系人的详细信息返回到我的应用程序。

我最近升级到 Phonegap 3.0，我正在尝试将我的插件转换为 3.0；但是我现在无法让插件工作，因为它都是 3.0....这就是我所拥有的

ContactView.js

\assets\www\js\android\ContactView.js

cordova.define("com.huronasolutions.plugins.ContactView", function (require, exports, module) {
    var exec = require("cordova/exec");

    var contactView = {
        show: function (successCallback, failCallback) {

            function success(args) {
                if (typeof successCallback === 'function')
                    successCallback(args);
            }

            function fail(args) {
                if (typeof failCallback === 'function')
                    failCallback(args);
            }

            return exec(
                function (args) { success(args); },
                function (args) { fail(args); },
                'ContactView',
                'getContact',
                []);
        }
    }
    module.exports = contactView;

});

我的 index.html 文件的头部有以下内容

<script type="text/javascript" src="js/android/ContactView.js"></script>

当我像这样在我的代码中调用它时

window.contactView.show(
               function (contact) {
                   success({ "contact": contact, "msg": "success" });
               },
               function (fail) {
                   fail({ "msg": "We were unable to get the contact you selected." });
               }
           );

我在 LogCat 中收到以下错误

*09-17 22:09:24.285：E/Web 控制台（1679）：未捕获的类型错误：无法调用未定义的“显示”方法 file:///android_asset/www/js/txt2.js:477*

当我这样称呼它时

 contactView.show(
                   function (contact) {
                       success({ "contact": contact, "msg": "success" });
                   },
                   function (fail) {
                       fail({ "msg": "We were unable to get the contact you selected." });
                   }
               );

LogCat 说 contactView 未定义。

有人可以帮忙吗，我想我已经遵循了我可以在网上找到的所有指南。 谢谢

Answer 1

像这样调用你的插件：

cordova.require("com.huronasolutions.plugins.ContactView").show(
 function (contact) {
   success({ "contact": contact, "msg": "success" });
 },
 function (fail) {
   fail({ "msg": "We were unable to get the contact you selected." });
 }
);

还要确保您已在 config.xml 中定义了插件：

<feature name="contactView">
      <param name="android-package" value="com.huronasolutions.plugins.ContactView"/
</feature>
